Copeland 918-0056-05 Crankcase Heater 320788-704 specific high-altitude pressure switches mayMaintain peak compressor reliability during the off cycle with the Copeland 918 0056 05 Crankcase Heater. This 480V 120W belt type heater is engineered specifically for Copeland ZR250 compressors and high tonnage industrial refrigeration systems. In low ambient conditions, refrigerant naturally migrates to the coldest part of the circuitthe compressor oil. Without a functional belly band heater, this results in flooded starts, oil dilution, and
